PNEUMATIC `ANNUNCI/WOR.

SPECIFICATION forming part of Letters PatentNo. 384,144, dated J' une 5, 1888.

Application filed Muy 13, 1P87.

.T aZZ whom it may concern:

Beit known that 1, ROBERT P. GARsED, a citizen of the United States, residing at Norristown, in the county of Montgomery', State of 5 Pennsylvania, have invented a new and useful Improvement in Pneumatic Anuunciators, which improvement is fully set forth in the following specification and accompanying drawings.

ro My invention'consists ofa pneumatic annunciator in which an annunciator dial or plate may be readily operated, as will be hereinafter fully set forth.

It also consists of means for ringing a bell or sounding an alarm, and thus directing attention to the operation of the annunciator, asA

will be hereinafter fully set forth.

Figure l represents a front View of au annunciator embodying my invention. Fig. 2 represents a partial vertical section and partial side elevation thereof.

Similar letters of reference indicate corresponding parts in the two figures.

Referring now to the drawings, A represents a plate or board which is located in the office of a hotel or other apartment, and formed with a series of inclined openings, a, through which are passed the arms B, which carry on the front or outer ends the dials or annunciator-plates C, which, as will be seen, are numbered, or may have other indicating characteristics usual in annunciators.

To the rear end of each arm B is secured a knob or ball, D, which is adapted to be en- 3 5 gaged by a cup or socket, E, on the top of an inflatable body or bellows, F, the latter being attached to and communicating with abranch pipe, G, of the main air-pipe H of the device, said pipe H having as many branch pipes as 4o there are dials or plates C to be operated.

Connected with the branch pipes G are tubes J, which extend from the various apartments of the hotel, Suc., and form communication between said apartments and the annunciator.

interposed between the place of connection of the pipes GJ and the main pipeHare checkvalves K,which prevent improper entrance of air into the branch pipes G.

Connected with the top of the main pipe H, 5o and in communication therewith, is a pipe,` L, to which is attached an inflatable body or bel- Serial No. 238.005. (No model.)

lows, M. Connected with said bellows M at the top thereof is the tripping-leverN of the hammer P of the bell or gong Q, which is properly supported above or adjacent tothe board A.

The operation is as follows: The pull or lever of an airpump in the apartment from which it is desired to have attention or make a call is moved, or other means are employed whereby air is forced through the respective pipe J, and consequently through the connected branch pipe G, so that the bellows Fis inliated and the cup E rises. The ball D is engaged by said cup E, so that the arm B is thrown outwardly and downwardly, and the attached plate C'drops with the same,which in valve K of the respective branch pipe G opens, but the check-valves of the other branch pipes are held closed on their seats. Air enters the main pipe H, but is prevented by said check- Through the pipe L the bellows M is iniiated, whereby, by means of the lever N, thehammer P is operated and the bell or gong Q struck, thus directing attention to the operation of the annunciator, especially to the dial 8, that has been displaced. By pushing back said dial `it is restored to its normal position, the arm Bby gravity, owing to the knob or weight D on the inner end thereof, holding the dial against the board A.

It will be understood that the device may be operated by the entrance of air from one branch pipe, or from a number or all of the branch pipes at the same time, whereupon the bell acts the same in any case, the dials or plates C showing the rooms calling.

The pipe H may be denominated as the main container for air.

The devices hereinbefore set forth are shown and described in an application for patent, Serial No. 81,126, led by me on the 6th day of January, A. D. 1883.,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A pneumatic annuuciator consisting of a main pipe with branch pipes, air-supply pipes connected with the branch pipes, bellows attached to the branch pipes, a dialcarrying arm operated by said bellows,and cheek-valves the present case is numbered 8. The checkvalve from entering the other branch pipes. l

in the branch pipes, the parts being combined substantially as described.

2. In a pneumatic annunciator, the combination of the main pipe H, having an alarm connected therewith, the pipes G, having one end closed and the other leading into the main pipe H, the air-supply tubes J, leading into pipe G, the checlvvalves K, located at the con nection of pipe G and main pipe H, and mechanism, substantially as described, connected to said main pipe and alarm, whereby the inlet of air into said main pipe operates the alarm, substantially as described.

3. A pneumatic annu'nciator consisting of a board with an inclined opening therein, arm B, passing through said opening and having the dial C on the front end and the ball D on the rear end thereof, the tube J, with airpump, the branch pipe G, connected with said tube, and the intiated body F,with socket or cup E thereon, said parts being combined substantially as and for the purpose set forth.

4. In a pneumatic annunciator, the main pipe H,Witl1 the pipe L, iniiated body M, a gong with hammer, and tripping device therefor, in combination with the branch tube G, having check-valve K, the inflated body F, with socket E, a board with an opening, and an arm passing through said opening, and haw ing a dial on its front end and a ball or knob on its rear end, said ball operating in said socket, substantially as described.

5. A pneumatic annunciator consisting of a board with a series of inclined openings there in, arms passing through said openings and having dials at their front ends adapted to close said openings, a main pipe, branch tubes connected with said main pipe, separate tubes leading to each of said branch tubes from airpumps, a check-valve in each of said branch tubes between said main pipe and air-pump tube, the said arms having pivotal connection with iniiated bodies on said branch tubes, and an alarm connected to said main pipe, said parts being combined substantially as and for the purpose set forth.
